Competition and solidarity: union members and immigration in Europe

Abstract:

This article addresses an understudied question in the comparative political economy of migration. How have trade unions shaped the attitudes of their members toward immigration? Unions are at the core of left-wing politics in most European countries, and support for immigration is usually a left-wing position. However, many of the core constituents of unions are those whose interests are most likely to be adversely affected by an increase in the supply of labour. The article shows that the pattern of European trade union leaders becoming supportive of open immigration policies has solidified over the past decade. It then provides evidence that this rhetoric has shaped the attitudes of union members and that the effect has become stronger over time. Finally, it shows that the effect is robust to the exclusion of countries where self-selection into unions on the basis of ideology is likely to be strongest.
